ABSTRACT

Systems, methods, and computer-readable media are disclosed for capturing gaze data for a sports participant over the course of a sports match, identifying a key performance indicator (KPI) corresponding to a sports domain with which the sports match is associated, and generating KPI data corresponding to the KPI. Report data indicative of the KPI data may be generated and presented to the sports participant in-match or post-match. KPI data for a player may be aggregated across multiple sports domain KPIs and multiple sports matches and analyzed to determine player activity patterns. The player activity patterns may indicate statistical differences in KPIs for the player in relation to different in-match scenarios. Recommendations may be provided to the player for improving the player&#39;s performance with respect to various KPIs.

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is related to co-pending application entitled “Analyzing and Interpreting a Referee's Actions Using Gaze Data,” having attorney docket number YOR920160283US1, and to co-pending application entitled “Analyzing Team Game Play Interactions Using Gaze Data,” having attorney docket number YOR920160284US1.

BACKGROUND

Participants in a sports match (also referred to as a game, contest, or the like) may have different skill levels that may impact their performance in response to different situations that may arise during the match. Parameters that may impact a sports participant's skill level may include, for example, reaction time, response time, attentiveness, hand-eye coordination, and so forth. These parameters may vary across sports participants, and may also vary for a given sports participant throughout a match depending on the particular situation that the participant encounters. For example, a left-handed baseball player may exhibit a faster reaction and response time when batting against a left-handed pitcher as opposed to a right-handed pitcher. In addition, a sports participant's response to a particular situation may vary over time throughout the match. For example, a tennis player's attentiveness may vary over time causing certain backhand returns to be struck with greater accuracy than other backhand returns.

A sports participant is generally unaware during a sports match of how his/her performance is statistically different for different scenarios that may arise during the match. While a sports participant may be aware of certain macro-level statistics (e.g., number of 2 point field goals made vs. 3 point field goals made during a basketball game), statistical data indicating differences in reaction/response times, attentiveness, etc. for different in-match scenarios is unavailable. Further, while video of a sports match may be viewed and assessed post-match, such analysis fails to elucidate granular differences in performance characteristics over the course of the match for the multitude of match scenarios that may occur. Discussed herein are technical solutions that address at least some of the aforementioned drawbacks as well as other drawbacks.

SUMMARY

In one or more example embodiments of the disclosure, a computer-implemented method for determining player performance statistics using gaze parameter data is disclosed. The method includes capturing, by an image sensor over a period of time, the gaze parameter data, where the gaze parameter data is associated with a participant in a sports match. The method further includes identifying, by a computer processor, a sports domain associated with the sports match and identifying, by the computer processor, a key performance indicator (KPI) corresponding to sports domain. The method additionally includes identifying, by the computer processor, one or more sports domain rules associated with the KPI and filtering, by the computer processor, the gaze parameter data to obtain a location/time series of the gaze parameter data that satisfies the one or more sports domain rules.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 1, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 1 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 2, a set of functional abstraction layers provided by cloud computing environment 50 (FIG. 1) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 2 are intended to be illustrative only and embodiments of the invention are not limited thereto. As depicted, the following layers and corresponding functions are provided:

Hardware and software layer 60 includes hardware and software components. Examples of hardware components include: mainframes 61; RISC (Reduced Instruction Set Computer) architecture based servers 62; servers 63; blade servers 64; storage devices 65; and networks and networking components 66. In some embodiments, software components include network application server software 67 and database software 68.

Virtualization layer 70 provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers 71; virtual storage 72; virtual networks 73, including virtual private networks; virtual applications and operating systems 74; and virtual clients 75.

In one example, management layer 80 may provide the functions described below. Resource provisioning 81 provides dynamic procurement of computing resources and other resources that are utilized to perform tasks within the cloud computing environment. Metering and Pricing 82 provide cost tracking as resources are utilized within the cloud computing environment, and billing or invoicing for consumption of these resources. In one example, these resources may include application software licenses. Security provides identity verification for cloud consumers and tasks, as well as protection for data and other resources. User portal 83 provides access to the cloud computing environment for consumers and system administrators. Service level management 84 provides cloud computing resource allocation and management such that required service levels are met. Service Level Agreement (SLA) planning and fulfillment 85 provide pre-arrangement for, and procurement of, cloud computing resources for which a future requirement is anticipated in accordance with an SLA.

FIG. 3 is a schematic block diagram depicting illustrative components of a three-dimensional (3D) gaze-based player analysis system in accordance with one or more example embodiments of the disclosure. FIG. 4 is a process flow diagram of a method 200 for generating key performance indicator (KPI) data associated with a sports domain KPI based at least in part on gaze parameter data in accordance with one or more example embodiments of the disclosure. FIG. 3 is a process flow diagram of a method 300 for analyzing aggregate KPI data to determine player activity patterns in accordance with one or more example embodiments of the disclosure. FIG. 3 will be described in conjunction with FIG. 4 and FIG. 3 hereinafter.

One or more operations of the methods 200 and 300 may be performed by one or more engines, or more specifically, by one or more program modules or sub-modules forming part of such engine(s). A module, which may contain or be a collection of one or more sub-modules, may include computer-executable instructions that when executed by a processing circuit may cause one or more operations to be performed. A processing circuit may include one or more processing units or nodes. Computer-executable instructions may include computer-executable program code that when executed by a processing unit may cause input data contained in or referenced by the computer-executable program code to be accessed and processed to yield output data. Any module described herein may be implemented in any combination of software, hardware, and/or firmware. Depending on the implementation, any module described herein may form part of a larger collection of modules that together may constitute an engine, an application, or the like.

Referring first to FIG. 3, a 3D gaze-based player analysis system in accordance with one or more example embodiments of the disclosure may include an eye gaze tracking engine 104, a sports match tracking and analysis engine 106, a player analysis engine 108, and a sport domain rules/sport KPI loading engine 110. Each such engine may include computer-executable instructions configured to perform one or more corresponding operations responsive to execution by a processing circuit.

The eye gaze tracking engine 104 may include one or more 3D gaze tracking module(s) 112 which, in turn, may include one or more gaze direction determination module(s) 114, one or more fixation duration determination module(s) 116, and one or more distance determination module(s) 118. The 3D gaze tracking module(s) 112 may be configured to monitor various gaze parameters associated with a participant 102 in a sports match. The sports match participant may be, for example, a player competing individually or as part of a team in the sports match. The sports match may be any suitable game or match including, without limitation, a team-based game or match in which two opposing teams compete, each team including a plurality of players (e.g., a soccer match, a baseball game, a cricket match, a basketball game, a football game, etc.); a game or match in which two individuals compete against one another (e.g., a tennis match, a table tennis match, etc.); a game in which an individual competes with one or more other individuals but does not directly interact with the other individual(s) (e.g., a golf tournament); and so forth.

Referring now to FIGS. 3 and 4 in conjunction with one another, at block 202, the 3D gaze tracking module(s) 112 may be executed to monitor various gaze parameters associated with the player 102 during a sports match and generate gaze parameter data 120 continuously or at periodic intervals of a specified granularity. The gaze parameter data 120 may include, for example, gaze direction data, gaze fixation duration data, and gaze distance data. The gaze parameter data 120 may be stored in a gaze parameter data repository 122. The gaze parameter data 120 may be captured in real-time during the sports match, or alternatively, may be captured (potentially post-match) based at least in part on an image analysis performed on a video of the sports match.

For instance, the gaze direction determination module(s) 114 may be executed to monitor a gaze direction of the player 102 to generate the gaze direction data, which may indicate how the direction of the player's gaze changes over time. This may be achieved using a camera that captures images of the player's 102 head over time at a particular frame rate. For each image frame, the gaze direction determination module(s) 114 may determine the angle of the player's 102 head with respect to the camera, and may further determine the position of the player's 102 eyes with respect to the player's head 102. The gaze direction determination module(s) 114 may then perform this determination repeatedly across all image frames to determine a scan path that indicates how the direction of the player's 102 gaze changes over time.

The fixation duration determination module(s) 116 may be executed to determine a respective duration of time that the player's 102 gaze remains in each particular gaze direction. The fixation duration determination module(s) 116 may output gaze fixation duration data that includes a series of time durations, where each time duration represents an amount of time that the player's 102 gaze remains in a particular gaze direction.

The distance determination module(s) 118 may be executed to determine distances between points of gaze of the player 102 and objects of interest. Depending on the particular sports domain KPI that is being evaluated, an object of interest may be a ball, bat, racket, shuttlecock, or other object that the player 102 interacts with during the sports match. The distance determination module(s) 118 may determine a three dimensional distance between the player 102 and an object of interest for each gaze direction of the player 102 and may generate gaze distance data indicative thereof.

As previously noted, the 3D gaze-based player analysis system may include a player analysis engine 108 that may include computer-executable instructions that when executed by a processing circuit may cause operations to be performed to generate an analysis model for interpreting the gaze parameter data 120 within a sports domain by translating a location/time series 124 of the gaze parameter data 120 into KPI data 144 associated with KPIs 140 that are relevant to the sports domain. More specifically, the player analysis engine 108 may include one or more gaze to sport domain KPI mapping modules 130 (hereinafter “mapping module(s) 130)) that may include computer-executable instructions that when executed by a processing circuit may determine gaze-based KPIs from the location/time series gaze parameter data 124 and translate the gaze-based KPIs into KPI data 144 that is relevant to a particular sports domain. The gaze-based KPIs may include, for example, any of the gaze parameters previously described including, but not limited to, the player's 102 gaze direction, the player's 102 gaze duration for a gaze direction, a distance between the player 102 and an object of interest for a particular gaze direction, etc.

Each sports domain may define a plurality of different sport domain KPIs 140 and associated sport domain rules 138. The KPIs 140 and associated domain rules 138 may be loaded into a repository 142 by the sports domain rules/sports KPI loading engine 110, and retrieved therefrom by mapping module(s) 130. Each sports domain may correspond to a particular type of sport, and the mapping module(s) 130 may be configured to translate gaze KPIs into sport domain KPIs for any number of sports domains.

Each sports domain KPI 140 for a given sports domain may be a particular type of performance indicator and may correspond to a particular event that may occur within that sports domain. Each sports domain KPI 140 may further be associated with a particular location or set of locations defined within a playing environment. In addition, each sports domain KPI 140 may be associated with a set of one or more sport domain rules 138 that define condition(s) based on which the gaze parameter data 120 may be filtered to obtain location/time series gaze parameter data 124 that satisfies the sports domain rule(s) 138.

In addition to accessing the repository 142 to obtain the sports domain KPIs 140 and associated sports domain rules 138, the player analysis engine 108 may also receive sports match data 126 as input from the sports match tracking and analysis engine 106. More specifically, the sports match data 126 may be input to the sports match tracking and analysis engine 106 via a user interface 128, and the engine 106 may provide the data 126 as input to the player analysis engine 108. The sports match data 126 may include data indicative of a time of a sports match, a location of the sports match, environmental conditions present at the location of the sports match (e.g., temperature, precipitation, wind speed, etc.). The sports match data 126 may be used by the player analysis engine 108 to determine, for example, how the sport KPIs 140 for the player 102 are impacted by different sports match locations, different times of day at which the sports match takes place, and/or different environmental conditions in which the sports match occurs.

The process performed by the mapping module(s) 130 for translating a location/time series 124 of the gaze parameter data 120 into KPI data 144 associated with KPIs 140 that are relevant to a sports domain will be described hereinafter in reference to a particular player (e.g., the player 102) and a particular sports domain KPI 140 associated with a particular sports domain. It should be appreciated, however, that the process may be performed for any number of players and any number of KPIs 140 associated with any number of sports domains.

Referring again to FIGS. 3 and 4 in conjunction with one another, at block 204, computer-executable instructions of the mapping module(s) 130 may be executed to identify a sports domain KPI 140 associated with a sports domain to which the sports match corresponds. The sports domain KPI 140 identified at block 204 may include, for example, a reaction time of a player (e.g., the amount of time it takes for the player 102 to detect an object of interest such as a ball or another player); a response time of a player (e.g., the amount of time that elapsed between when the player 102 detects an object of interest and provides a response such as the amount of time that elapses between when a batter detects a ball that has been pitched and contacts the ball with a bat); a metric indicating a degree of attentiveness of a player (e.g., a gaze direction of the player 102 when an event corresponding to the sports domain KPI occurs); or the like.

As previously described, each sports domain KPI 140 may be defined with respect to a corresponding type of event. Taking the sport of soccer as an example, the events may include, without limitation, a foul, a throw-in, a center, an indirect free kick, a direct free kick, a penalty kick, a header, a corner kick, and so forth. As another example, in tennis, the events may include, without limitation, a serve, a volley, a baseline shot, a forehand, a backhand, a cross-court shot, a down-the-line shot, a passing shot, an overhead smash, an approach, and so forth.

Further, each sports domain KPI 140 may be defined with respect to one or more locations. Referring again to soccer as an example, the locations may include, without limitation, an out-of-bounds line, a penalty box, a mid-field line, a goal-line, a particular portion of a soccer field (e.g., midfield), and so forth. As another example, in tennis, the locations may include, without limitation, the baselines, the sidelines, the line separating the deuce and advantage courts, the net, and so forth.

At block 206, the mapping module(s) 130 may identify one or more sports domain rules associated with the sports domain KPI identified at block 204. The sports domain rule(s) 138 associated with a given sports domain KPI 140 may include one or more conditions that the gaze parameter data 120 must satisfy in order to eligible for translation into the KPI data 144 corresponding to the sports domain KPI 140 for that sports domain. For instance, for a sports domain KPI 140 corresponding to a foul in soccer, an associated sports domain rule 138 may specify that the mapping module(s) 130 must analyze gaze parameter data 120 for the player 102 obtained during the time period that is x seconds prior to the time the foul occurs as well as the moment the foul occurs.

In certain example embodiments, a sports domain rule 138 may also specify criteria that must be met in order to authenticate or reject a decision made by a referee. For example, a sports domain rule 138 may specify that the player's 102 attention (as determined from the gaze parameter data 120) must be within a circle centered at the location of a foul and having a diameter of m feet or yards for at Y % of the x seconds prior to the foul referenced earlier. If this sports domain rule 138 is satisfied, the foul may be confirmed, whereas if this sports domain rule 138 is not satisfied, the referee's decision to call the foul may be overturned.

At block 208, the mapping module(s) 130 may determine a location/time series 124 of the gaze parameter data 120 that satisfies the sports domain rule(s) 138 identified at block 206. As an example, if the sports domain KPI 140 identified at block 204 is the focus/attentiveness of the player 102 returning the service of another player in a tennis match, and an associated sports domain rule 138 identified at block 206 specifies that a time period beginning 2 seconds before the service and ending when the ball hits the player's 102 side of the court should be monitored, the location/time series 124 of the gaze parameter data 120 that satisfies the sports domain rule 138 may include the gaze direction data, gaze duration data, and gaze distance data for the player 102 that is captured during that time period.

At block 210, the mapping module(s) 130 may translate the location/time series gaze parameter data 124 determined to satisfy the sports domain rule(s) 138 into the KPI data 144 associated with the sports domain KPI 140 identified at block 206. Taking the sports domain of tennis as an example again, the mapping module(s) 130 may translate the location/time series gaze parameter data 124 into the KPI data 144 for a reaction/response time KPI 140 in the following manner. The mapping module(s) 130 may first determine the trajectory of the ball. The mapping module(s) 130 may then determine a gaze vector for the player 102, where the gaze vector represents a series of gaze directions over time. The mapping module(s) 130 may then determine an intersection between the gaze vector and the trajectory path of the ball and determine a time corresponding to the intersection, which may be the reaction time for the player 102. The mapping module(s) 130 may then compute a response time for the player 102 as the time that elapses between when reaction time and when the player 102 makes contact with the ball.

At block 212, the player current activity analysis module(s) 134 may be executed by a processing circuit to cause the KPI data 144 to be analyzed to determine current activity trends of the player 102. Then, at block 214, computer-executable instructions of the report generation module(s) 136 may be executed by a processing circuit to generate report data indicative of the current activity trends of the player 102. The report data may be presented to the player 102 in real-time during the sports match to allow the player 102 to adjust his/her behavior to continue certain trends and/or reverse other trends.

As an example, assume that Roger Sampras and Rafael Agassi are competing in a tennis match. Roger Sampras returns a high percentage of Rafael Agassi's serves in the first set of the match, but begins missing a greater percentage of Agassi's serves in the second set. The mapping module(s) may be executed to generate KPI data 144 for Roger Sampras relating to his focus/attentiveness in connection with Agassi's service. As previously described, this KPI data 144 may be generated by translating gaze parameter data 120 for Roger Sampras into one or more sports KPIs 140 relevant to the tennis sports domain and associated with a service event.

The player current activity analysis module(s) 132 may then analyze this KPI data 144 to identify current activity trends for Roger Sampras in relation to Agassi's serve. For example, the current activity trends may indicate that Sampras' gazing behavior illustrates the his focus (e.g., gaze direction) was more towards the hands, wrist, or racket of Agassi at the moment of release of Agassi's serve in the first set, whereas Sampras' focus had moved more towards Agassi's feet at the moment of Rafael Agassi's service release in the second set.

The current activity trends of Sampras in relation to Agassi's serve may be presented to Sampras during the match, thereby allowing Sampras adjust his gazing behavior in the third set by consciously directing his gaze towards Agassi's hands, wrist, or racket at the moment of release of Agassi's serve, and thereby once again increase the percentage of Agassi's serves that he returns.

As another example, assume that the Alex Jeter is a batter who has faced a particular pitcher (Greg Smoltz) three times in a baseball game already. Further, assume that the Jeter has struck out against the Smoltz in two of his previous three plate appearances and hit a home run in the other plate appearance. The mapping module(s) 130 may be executed to generate KPI data 144 for Jeter relating to his reaction/response time and his focus/attentiveness between when Smoltz winds up his pitch and when Smoltz releases the pitch. As previously described, this KPI data 144 may be generated by translating gaze parameter data 120 for Jeter into one or more sports KPIs 140 relevant to the baseball sports domain and associated with a pitching event.

The player current activity analysis module(s) 132 may then analyze this KPI data 144 to identify current activity trends for Jeter in relation to Smoltz's pitching. For example, the current activity trends may indicate that Jeter's gazing behavior illustrates that his focus (e.g., gaze direction) was towards the point of release of the pitch that was hit for a home run, but had moved farther away from the point of release for the two plate appearances during which he struck out. The current activity trends may further indicate, for example, that Jeter's gaze direction intersected with the trajectory of the ball when he made contact with the ball resulting in a home run, but that his gaze direction did not intersect with the trajectory of the ball at the moment that the bat and the ball occupied a same plane during the two plate appearances that Jeter struck out.

The current activity trends for Jeter in relation to Smoltz's pitching may be presented to Jeter prior to his fourth plate appearance, thereby allowing Jeter to adjust his gazing behavior during his fourth plate appearance by consciously directing his gaze towards the point of release of Smoltz's pitch as well as directing his gaze towards the ball as he attempts to make contact with the ball. In this manner, the likelihood that Jeter strikes out during his fourth plate appearance may be reduced.

Referring now to FIGS. 3 and 5 in conjunction with one another, in addition to determining current activity trends, the KPI data 144 generated for the player 102 may be aggregated for multiple sports KPIs 140 over multiple sports matches to determine aggregate activity trends for the player 102. At block 302, the player aggregate activity analysis module(s) 134 may be executed by a processing circuit to obtain aggregate KPI data for the player 102, the aggregate KPI data corresponding to a plurality of sports domain KPIs over a plurality of sports matches. Using the tennis sports domain as an example, the aggregate KPI data may correspond to reaction/response times, focus/attentiveness metrics, etc. for a variety of different events such as, for example, any of the example events previously described in connection with the tennis sports domain.

At block 304, the player aggregate activity analysis module(s) 134 may be executed to analyze the aggregate KPI data to determine player activity patterns. Using the tennis sports domain as an example again, the player activity patterns may include, for example, a gazing behavior pattern when the player 102 commits an unforced error, a gazing behavior pattern when the player 102 hits a winner, and so forth. Each of these player activity patterns may be further broken down into sub-patterns for different sub-events. For example, the gazing behavior pattern when the player 102 commits an unforced error may be further broken down into a gazing behavior pattern when the player 102 fails to make contact with the ball vs. a gazing behavior pattern when the player 102 makes contact but hits the ball out-of-bounds.

At block 306, the report generation module(s) 136 may be executed to generate report data that identifies the player activity patterns. The report data may be presented to the player 102, and the player 102 may utilize the report data to assess his/her tendencies and take corrective measures. It should be appreciated that the player 102 may exhibit different player activity patterns for different opponents. The report data may reflect these different patterns for different opponents, thereby allowing the player 102 to tailor his/her play more effectively based on the opponent.
